                <h4 id="preamble">Preamble</h4>

                <p>
                    The licenses for most software are designed to take away your
                    freedom to share and change it. By contrast, the GNU General Public
                    License is intended to guarantee your freedom to share and change free
                    software--to make sure the software is free for all its users. This
                    General Public License applies to most of the Free Software
                    Foundation's software and to any other program whose authors commit to
                    using it. (Some other Free Software Foundation software is covered by
                    the GNU Lesser General Public License instead.) You can apply it to
                    your programs, too.
                </p>

                <p>
                    When we speak of free software, we are referring to freedom, not
                    price. Our General Public Licenses are designed to make sure that you
                    have the freedom to distribute copies of free software (and charge for
                    this service if you wish), that you receive source code or can get it
                    if you want it, that you can change the software or use pieces of it
                    in new free programs; and that you know you can do these things.
                </p>

                <p>
                    To protect your rights, we need to make restrictions that forbid
                    anyone to deny you these rights or to ask you to surrender the rights.
                    These restrictions translate to certain responsibilities for you if you
                    distribute copies of the software, or if you modify it.
                </p>

                <p>
                    For example, if you distribute copies of such a program, whether
                    gratis or for a fee, you must give the recipients all the rights that
                    you have. You must make sure that they, too, receive or can get the
                    source code. And you must show them these terms so they know their
                    rights.
                </p>

                <p>
                    We protect your rights with two steps: (1) copyright the software, and
                    (2) offer you this license which gives you legal permission to copy,
                    distribute and/or modify the software.
                </p>

                <p>
                    Also, for each author's protection and ours, we want to make certain
                    that everyone understands that there is no warranty for this free
                    software. If the software is modified by someone else and passed on, we
                    want its recipients to know that what they have is not the original, so
                    that any problems introduced by others will not reflect on the original
                    authors' reputations.
                </p>

                <p>
                    Finally, any free program is threatened constantly by software
                    patents. We wish to avoid the danger that redistributors of a free
                    program will individually obtain patent licenses, in effect making the
                    program proprietary. To prevent this, we have made it clear that any
                    patent must be licensed for everyone's free use or not licensed at all.
                </p>

                <p>
                    The precise terms and conditions for copying, distribution and
                    modification follow.

                <h4 id="terms">TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</h4>

                <p id="section0">
                    <strong>0.</strong>
                    This License applies to any program or other work which contains
                    a notice placed by the copyright holder saying it may be distributed
                    under the terms of this General Public License. The "Program", below,
                    refers to any such program or work, and a "work based on the Program"
                    means either the Program or any derivative work under copyright law:
                    that is to say, a work containing the Program or a portion of it,
                    either verbatim or with modifications and/or translated into another
                    language. (Hereinafter, translation is included without limitation in
                    the term "modification".) Each licensee is addressed as "you".
                </p>

                <p>
                    Activities other than copying, distribution and modification are not
                    covered by this License; they are outside its scope. The act of
                    running the Program is not restricted, and the output from the Program
                    is covered only if its contents constitute a work based on the
                    Program (independent of having been made by running the Program).
                    Whether that is true depends on what the Program does.
                </p>

                <p id="section1">
                    <strong>1.</strong>
                    You may copy and distribute verbatim copies of the Program's
                    source code as you receive it, in any medium, provided that you
                    conspicuously and appropriately publish on each copy an appropriate
                    copyright notice and disclaimer of warranty; keep intact all the
                    notices that refer to this License and to the absence of any warranty;
                    and give any other recipients of the Program a copy of this License
                    along with the Program.
                </p>

                <p>
                    You may charge a fee for the physical act of transferring a copy, and
                    you may at your option offer warranty protection in exchange for a fee.
                </p>

                <p id="section2">
                    <strong>2.</strong>
                    You may modify your copy or copies of the Program or any portion
                    of it, thus forming a work based on the Program, and copy and
                    distribute such modifications or work under the terms of Section 1
                    above, provided that you also meet all of these conditions:
                </p>

                <dl>
                    <dt></dt>
                    <dd>
                        <strong>a)</strong>
                        You must cause the modified files to carry prominent notices
                        stating that you changed the files and the date of any change.
                    </dd>
                    <dt></dt>
                    <dd>
                        <strong>b)</strong>
                        You must cause any work that you distribute or publish, that in
                        whole or in part contains or is derived from the Program or any
                        part thereof, to be licensed as a whole at no charge to all third
                        parties under the terms of this License.
                    </dd>
                    <dt></dt>
                    <dd>
                        <strong>c)</strong>
                        If the modified program normally reads commands interactively
                        when run, you must cause it, when started running for such
                        interactive use in the most ordinary way, to print or display an
                        announcement including an appropriate copyright notice and a
                        notice that there is no warranty (or else, saying that you provide
                        a warranty) and that users may redistribute the program under
                        these conditions, and telling the user how to view a copy of this
                        License. (Exception: if the Program itself is interactive but
                        does not normally print such an announcement, your work based on
                        the Program is not required to print an announcement.)
                    </dd>
                </dl>

                <p>
                    These requirements apply to the modified work as a whole. If
                    identifiable sections of that work are not derived from the Program,
                    and can be reasonably considered independent and separate works in
                    themselves, then this License, and its terms, do not apply to those
                    sections when you distribute them as separate works. But when you
                    distribute the same sections as part of a whole which is a work based
                    on the Program, the distribution of the whole must be on the terms of
                    this License, whose permissions for other licensees extend to the
                    entire whole, and thus to each and every part regardless of who wrote it.
                </p>

                <p>
                    Thus, it is not the intent of this section to claim rights or contest
                    your rights to work written entirely by you; rather, the intent is to
                    exercise the right to control the distribution of derivative or
                    collective works based on the Program.
                </p>

                <p>
                    In addition, mere aggregation of another work not based on the Program
                    with the Program (or with a work based on the Program) on a volume of
                    a storage or distribution medium does not bring the other work under
                    the scope of this License.
                </p>

                    <strong>3.</strong>
                    You may copy and distribute the Program (or a work based on it,
                    under Section 2) in object code or executable form under the terms of

                        to distribute corresponding source code. (This alternative is
                        allowed only for noncommercial distribution and only if you
                        received the program in object code or executable form with such
                        an offer, in accord with Subsection b above.)

                <p>
                    The source code for a work means the preferred form of the work for
                    making modifications to it. For an executable work, complete source
                    code means all the source code for all modules it contains, plus any
                    associated interface definition files, plus the scripts used to
                    control compilation and installation of the executable. However, as a
                    special exception, the source code distributed need not include
                    anything that is normally distributed (in either source or binary
                    form) with the major components (compiler, kernel, and so on) of the
                    operating system on which the executable runs, unless that component
                    itself accompanies the executable.
                </p>

                <p>
                    If distribution of executable or object code is made by offering
                    access to copy from a designated place, then offering equivalent
                    access to copy the source code from the same place counts as
                    distribution of the source code, even though third parties are not
                    compelled to copy the source along with the object code.

                    distribute the Program or its derivative works. These actions are
                    prohibited by law if you do not accept this License. Therefore, by
                    modifying or distributing the Program (or any work based on the

                    original licensor to copy, distribute or modify the Program subject to
                    these terms and conditions. You may not impose any further
                    restrictions on the recipients' exercise of the rights granted herein.

                    excuse you from the conditions of this License. If you cannot
                    distribute so as to satisfy simultaneously your obligations under this
                    License and any other pertinent obligations, then as a consequence you
                    may not distribute the Program at all. For example, if a patent
                    license would not permit royalty-free redistribution of the Program by
                    all those who receive copies directly or indirectly through you, then
                    the only way you could satisfy both it and this License would be to
                    refrain entirely from distribution of the Program.

                    such claims; this section has the sole purpose of protecting the
                    integrity of the free software distribution system, which is
                    implemented by public license practices. Many people have made
                    generous contributions to the wide range of software distributed
                    through that system in reliance on consistent application of that
                    system; it is up to the author/donor to decide if he or she is willing
                    to distribute software through any other system and a licensee cannot
                    impose that choice.

                <p>
                    If you develop a new program, and you want it to be of the greatest
                    possible use to the public, the best way to achieve this is to make it
                    free software which everyone can redistribute and change under these terms.
                </p>

                <p>
                    To do so, attach the following notices to the program. It is safest
                    to attach them to the start of each source file to most effectively
                    convey the exclusion of warranty; and each file should have at least
                    the "copyright" line and a pointer to where the full notice is found.
                </p>

                    You should also get your employer (if you work as a programmer) or your
